PRODUCT DESCRIPTION
housing and actuator are made of high-quality stainless steel
switch is particularly suitable for use in equipment in harsh environments or for vandal-
protected applications
available with mounting diameters of 19 and 22 mm
suitable for use in temperatures ranging from -20 °C to+85 °C
permissible switching voltages up to 125 VDC / 250 VAC
switching status (ON/OFF) is easy to discern by looking at, or feeling, the resting position
of the actuator; in the off state, the actuator position protrudes from the housing; in the ON
state, it is depressed into the housing
with quick connect terminals to allow for fast connections
point and ring illuminated versions in red, green and blue are available for indicating the
switching status or for providing visibility during night-time use
available in single-pole and double-pole versions
