Lets face it folks, sometimes it just takes a plunger switch. Whether your application is mechanically or physically activated, the tactile feel, and extended actuator of a plunger switch may be the only real solution for your application. For engineers looking at a harsh duty, wet, outdoor application, you’ve landed in the right place. CPI plunger switches are recognized around the world as the premiere solution to harsh duty waterproof plunger and limit switch applications. If durability is your first priority in a plunger switch, consider these characteristics:
Manual Plunger Switches for Waterproof Applications In something like our D1040 Waterproof Plunger Switch, the plunger actuates one of our sealed pendent switches which is mounted firmly in a stainless steel housing. For this application we use one of our low-button momentary switches like our B2, B5, or B9 series, but any of our waterproof B series switches can be used. The final solution is completely waterproof, with custom leads and termination. An optional rubber plunger boot can also be added. This is also a perfect switch for many custom switch panel applications. Mechanical Plunger Applications.For the really harsh applications inside an engine block, or behind a vehicle hood or door as open detection, our J4 series plunger switches are the ultimate in survivable, reliable plunger switches. These switches are all stainless steel with an optional patented seal exclusion design which actually pushes out contaminants like dirt and dust from the housing with every switch depression. For high temperature applications our J4 plunger even comes with a heat-sink variation that allows for almost 400F operation at the plunger. This is our J4401 series, high temperature limit switch. For high temperature, high pressure, long travel applications, these switches withstand the most extreme operating conditions. No Limits on our plungers as manufacturers of high durability plunger switches for over 70 years, we’ve got the experience and field resume that insures your search for a reliable plunger switch ends here.

CPI Waterproof switches offer massive flexibilityOf course then there are a boatload of electrical, temperature, endurance, and ergonomic options you can specify for your basic waterproof panel mount switch. Just some of the customizable parameters of our panel mount switches include:
Waterproof Panel Mount Switches in ActionOver the years CPI has collected dozens of applications for its waterproof switch panels including:
Canned and Custom Switch Panel ProductsOver the years CPI has developed some standard panel configurations that meet 90% of the requests we get. These simple panels have one or two switches on them and can have wire lead lengths and terminations that are completely specifiable by the customer Common examples of this are our K1163-501 and K1164-501 Single and Dual Panels respectively, using variations of our high actuation high force pendant switch. High actuation is better for gloved operation and high actuation force insures that the switches wont easily be activated by accident. Panel Mounted Waterproof Pendant Switches for Your EquipmentIf you have a rough duty piece of equipment begging for a reliable waterproof switch, its highly likely we have an off the shelf product that far exceeds the reliability and capability of what you have now. And we can even stick it in a stainless steel waterproof panel for you Give CPI a call today to discuss your waterproof panel needs. This blog originally published at https://www.cpi-nj.com/blog/panel-mounted-switches-save-you-time-and-money/ Thermal switches were originally designed to be reliable, standalone, systems that encompassed both a sensing element, and a switch. At a chosen set-point these thermocouple devices would reliably close or open a contact allowing for critical systems to be protected or activated. They were very accurate, could detect at very high temperatures, could handle a good amount of current in their switches, and did not require intervention by operators or other control computers or systems. They were/are completely standalone control systems.
But the cost of producing and deploying thermal switches, along with evolution of computers and small thermal monitoring devices, inevitably meant that some applications for which thermal switches were the only game in down, would eventually go the way of sensors and remote computer control. Yet there are still two camps out there on this idea of sensors vs. switches, even within the same applications. Some engineers would not consider using a sensor while others don't have the reliability concerns and are happy to enjoy the lower cost of pure sensors connected to controls in their application. How does a good engineer sort it all out? When it Might Be Time to Consider Thermal Switches instead of SensorsWhile the value of sensors in many applications comes down to cost and sometimes size, there are still a number of reasons that engineers may prefer standalone thermal switches in their applications.
CPI Thermal SwitchesCPI makes three distinct lines of thermal switches, organized around the temperature ranges they serve. All represent hardened thermal implementations cultivated over a 70+ year period of field deployment in every imaginable environment, from jet aircraft, to plastics manufacturing, to submarines.
