    Surface-Mount Temperature Switches

    Image of Product. Front orientation. Temperature Switches. Surface-Mount Temperature Switches.
    Often used to control heat cable output, these switches maintain your surface’s temperature by turning equipment on or off when they reach a set temperature. They actuate when the temperature rises to the setpoint and reset when the temperature falls below the reset point. Since they're SPDT (single pole, double throw) switches, they control one circuit and can either be wired to turn one device from on to off (normally closed) or from off to on (normally open). Wire them normally closed to power a heater—when the temperature rises to the setpoint, the heater will turn off until the temperature falls below the reset point. Or wire them normally open to turn on alarms or other devices when the temperature rises above the setpoint. Their setpoint isn’t adjustable, so they’re easy to set up and there’s no risk of unintentional changes.
    CSA-US Certified—CSA-US certified switches meet American safety standards.

    An airtight seal on these switches blocks out dust, dirt and moisture. They maintain your surface’s temperature by turning equipment on or off when they reach a set temperature. These switches actuate when the temperature rises to the setpoint and reset when the temperature falls below the reset point. Since they're SPDT (single pole, double throw) switches, they control one circuit and can either be wired to turn one device from on to off (normally closed) or from off to on (normally open). Wire them normally closed to power a heater—when the temperature rises to the setpoint, the heater will turn off until the temperature falls below the reset point.

    Enclosure Thermostats for Multiple Devices

    Keep electronics in your enclosure from getting too hot or cold with these thermostats that control two devices at once. Clip them to a DIN rail to install.
    For Heating and Cooling Thermostats with One Actuation Point

    Adjustable Thermostat

    with One Actuation Point

    Heating and cooling thermostats control heaters and fans or air conditioners.
    Thermostats with one actuation point, also known as changeover thermostats, switch between heating and cooling so one device is always running. When the temperature in your enclosure gets hotter than the temperature you set, the thermostat will turn on your fan or air conditioner. It goes back to heating once the temperature is reduced by the temperature difference. So for a thermostat with a temperature difference of 9° F, setting it at 60° F means it will heat the enclosure until it reaches 60° F, switch to cooling until it reaches 51° F, and then switch back to heating.
    Adjustable Actuation Point—Adjustable thermostats allow you to set custom temperatures.
    IP20 Enclosure Rating—All thermostats meet IP20, which means they’re designed so fingers can’t fit inside and get shocked.
    UL 94 V-0—They also meet UL 94 V-0, so they self-extinguish within 10 seconds if they catch fire and won’t spread the fire by dripping.
    Certification—Thermostats that are CE marked or VDE certified meet European safety standards. UL Recognized Component and C-UL Recognized Component thermostats also meet American and Canadian safety standards.
