Honeywell's TS500 switches are ideally suited for applications where exceptional reliability, rapid temperature response, and consistently high quality are key requirements. They may be used to control, indicate or limit a variety of temperature functions.
These single pole, single throw switches are hermetically sealed using all-welded construction. A calibrated bimetal, snap-acting disc provides the energy to open and close electrical contacts at pre-specified temperature settings.
The TS500 switches are manufactured in a controlled environment with temperature setpoints tested by a computer to assure accuracy and uniformity. The discs are 100% tested prior to assembly.
Nine standard mounting configurations are available. They are
easily adaptable for special designs in industrial, aeronautic,
and military applications, and are qualified to MIL-PRF-24236/1.
