Limit Switches

HK244 and WK244

Momentary-contact limit switches

for low voltage circuit

HK244 and WK244

■ Description

HK244 and WK244 limit switches have

been developed for use in low voltage

and low current circuits. They will

operate effectively in 3 Volts AC or DC,

5mA circuits although they are

recommended that they are used in 48

Volts or 110 Volts circuits for best

results.

HK244 limit switches are provided with

pure silver contacts. The movable

contact carries out a scrubbing action

during make/break operation ensuring

good connections at all times.

The switch body is molded from a high

performance resin, and versions with

transparent plastic covers and with

aluminum die-cast housing are also

available.

The bifurcated contact is made of pure

silver and like the HK244 series they are

also suitable for use with low voltage

circuits. The dimensions and operating

strokes are similar to the standard type.
