Temperature responsive electrical switch device

A temperature responsive electrical switch device comprising:

• a housing;
• a cover associated with said housing and having a slot therein;
• guide means associated with said cover for defining a generally linear channel communicating with said slot;
• switching means disposed at least in part within said housing for actuation between a plurality of switching modes;
• actuating means operable generally for effecting the actuation of said switching means from one of the switching modes to another of the switching modes thereof;
• temperature responsive means for effecting the operation of said actuating means to actuate said switching means at a selected set point temperature for the device, said temperature responsive means including cam follower means for extending in part through said slot into said linear channel;
• and
• cam means linearly movable in said linear channel in response to a manually applied force exerted on said cam means and arranged in camming engagement with said cam follower means for setting the selected set point temperature.

A temperature responsive electrical switch device comprising:

• switch means operable generally for switching between a plurality of switching modes;
• actuating means operable generally for effecting the operation of said switch means from one of the switching modes to another of the switching modes thereof;
• temperature responsive means for effecting the operation of said actuating means to operate said switch means from the one switching mode to the another switching mode thereof generally at a selected set point temperature for the device;
• and
• means movable in response to a manually applied force exerted thereon and engaged with an associated part of said temperature responsive means for setting the selected set point temperature, said setting means including means responsive to the manually applied force movement of said setting means into a preselected position for effecting the operation of said actuating means independently of said temperature responsive means so as to releasably maintain said switch means in the another switching mode thereof.

A temperature responsive electrical switch device comprising:

• switching means for actuation between a pair of switching modes;
• switch actuating means operable generally for effecting the actuation of said switching means from one of the switching modes to the other of the switching modes thereof;
• temperature responsive means for effecting the operation of said switch actuating means to actuate said switching means generally at a selected set point temperature for the device;
• and
• means linearly movable in responsive to a manually applied force exerted thereon and arranged in camming engagement with an associated part of said temperature responsive means for setting the selected set point temperature, said setting means including cam means for camming engagement with a part of said switch actuating means to effect the actuation of said switching means independently of said temperature responsive means.

A temperature responsive electrical switch device comprising:

• switching means for actuation between a pair of switching modes;
• switch actuating means operable generally for effecting the actuation of said switching means from one of the switching modes to the other of the switching modes thereof;
• temperature responsive means for effecting the operation of said switching actuating means to actuate said switching means generally at a selected set point temperature for the device;
• means linearly movable in response to a manually applied force exerted thereon and arranged in camming engagement with an associated part of said temperature responsive means for setting the selected set point temperature, said setting means including a plurality of cam surfaces;
• said associated part of said temperature responsive means comprising a cam follower arranged in the camming engagement with one of said cam surfaces;
• and
• said switch actuating means including cam follower means for camming engagement with another of said cam surfaces to effect the operation of said switch actuating means to actuate said switching means independently of said temperature responsive means when said another cam surface is moved into the camming engagement with said cam follower means.
