Design

Being wholly open top, the perimeter loop movable contact is held in place by steps moulded into the shell. The case does not accept a diode, latching mechanism or LEDs: these features use separate designs of switch. The shell has space for a second stationary contact (including the required hole in the base for the terminal); this would allow for an SPST changeover switch with one contact normally open and one contact normally closed. 76 M SPDT is not known in any form, but RS 74 M SPDT latching does exist.

Variants

The 90 cN IP40 version has a white slider, while the 140 cN IP40 version has a yellow slider.
