Microswitches
Miniature Microswitch Introduction
Alcoswitch miniature microswitches are offered with many options to suit most typical
applications.
These switches are available in a current range from 16A to .1A. Additional options
available throughout the different current ratings include:
Pin Plunger
Short, normal and long lever
Short and normal roller
Simulated lever
SPDT, SPNO and SPNC circuitry
Within the 16A range, in addition to two different terminal options, there are three different
actuation force options.
You can count on this offering of switches to be high reliability and low cost to fulfill your
basic microswitch needs. Of course if you need something custom, we can offer that also.
Contact your Tyco Electronics sales engineer for details.
