Pushbutton Switches and Indicators
SWITCH MODULES
Interchangeable type 2D switch modules
attach to spring clips on the bottom of
operator-indicator housings. There is a
wide selection of circuitry, electrical rat-
ings, operating actions and terminations.
For mounting dimensions, see page 115.
Series 2
SM SUBMINIATURE MULTI-SPDT SWITCH MODULES
Momentary action
SM switch modules offer a choice of two
momentary action styles, one with a pro-
nounced touch-feedback, the other with
low operating force for rapid repeat ac-
Alternate action
tuation. Also available with alternate-
action and combination momentary/
alternate action modules. Extra length
turret solder terminals.

used with short-flange operator indica-
tors, add spacing barriers to prevent
interference.
