Designers of thermostats, motors and industrial controls need a highly-responsive, protected switch that can withstand repeated use. That’s why so many turn to C&K’s HB series single pole standard precision snap-acting switch. The HB series features low differential travel and high repeatability; comes in a sealed actuator and case; and is available with single and double pole circuitry, to ensure that thermostats and other controls respond to use the same way – regardless of whether it’s the first or the thousandth use.
