Abstract
A thermal switch housing is provided in a recessed lighting fixture for interchangeably accommodating a thermal cut-off switch to protect against overtemperature conditions. The housing allows thermal switches having differing cut-off temperatures to be interchangeably removed and inserted to adjust for variations in fixture design, such as the size, shape and materials of construction.
Claims16
An apparatus for interchangeably accommodating a thermal switch comprising:
- (a) a housing;
- (b) a channel disposed within said housing adapted to accommodate a thermal switch having an open or closed status, wherein said channel extends through a side of said housing to define a first access opening;
- (c) a pair of electrical contacts disposed within said housing and arranged along said channel to provide an electrical connection between said electrical contacts and terminals of said thermal switch;
- and
- (d) means for conductively connecting a pair of external electrical conductors to said electrical contacts wherein said thermal switch is interchangeably insertable through said first access opening into said channel such that an electrical path is established through said external electrical conductors when said thermal switch has been inserted and is in said closed status.

An apparatus for interchangeably accommodating a thermal switch comprising:
- (a) a cylindrical housing;
- (b) a channel disposed within said housing along a line defining the diameter of said cylindrical housing adapted to accommodate a thermal switch having an open or closed status, wherein said channel extends through opposite facing walls of said cylindrical housing to define first and second access openings;
- (c) a pair of electrical contacts disposed within said housing and diametrically disposed about said channel;
- and
- (d) means for connecting a pair of external electrical conductors to said electrical contacts wherein said thermal switch is interchangeably insertable through said first access opening into said channel and said external conductors enter through said second access opening and are fixedly and conductively secured to said electrical contacts such that an electric path is established through said external electrical conductors when said thermal switch has been inserted and is in said closed status.
