Abstract
A switch housing body has a base and a sidewall having an axis and extending from the base to a rim and having a pair of axial slots. A switch cap has: a cap body having a top web; and a sidewall extending from the top web to a rim and having a pair of holes. A shaft passes through the pair of axial slots and pair of holes. A spring biases the cap axially away from the housing from a compressed condition to an extended condition. A cap electrical contact and a housing electrical contact have an electrically closed condition at the compressed condition.

A switch comprising:
- a housing having a housing body comprising:
- a base;
- and
- a sidewall having an axis and extending from the base to a rim and having:
- an outer diameter surface having an external thread;
- and
- a pair of axial slots;
- a cap biased axially away from the housing along an axial range of motion from a compressed condition to an extended condition, the cap having:
- a cap body having:
- a top web;
- and
- a sidewall extending from the top web to a rim and having:
- a pair of holes;
- and
- a shaft passing through the pair of axial slots and pair of holes;
- and
- a cap electrical contact and a housing electrical contact respectively on the cap and the housing and having an electrically closed condition at the compressed condition.
A fixture for processing a part, the fixture comprising:
- a body having a plurality of threaded holes;
- a plurality of switches having:
- a housing body mounted in a respective associated hole of the plurality of threaded holes;
- and
- a part-engaging member for contacting the part in an installed condition of the part and mounted to the housing body for axial movement between a compressed condition and an extended condition, the part-engaging member biased from the compressed condition toward the extended condition;
- a housing body electrical contact;
- and
- a part-engaging member electrical contact for contacting the housing body electrical contact in the compressed condition;
- and
- at least one clamp for holding the part in the installed condition.
