Status: active
Page Count: 21
scope:

This specification covers the general requirements for metallic-element actuated, thermostatic switches intended primarily for use in electrical and electronic equipment, in alternating current (ac) and direct current (dc) applications, where temperature protection, overheat detection, or accurate temperature control is required. The operating temperatures and operating temperature ranges of switches are covered by this specification (see 3.1 and 6.2.2).

Classification. Switches covered by this specification are to be classified by type and class as indicated herein (see 3.1 and 6.2.2).

Type I - Snap action, make and break operation.

Type II - Slow make and break operation.

Class 1 - Altitude - Sea level to 10,000 feet. Vibration - 10-55 Hertz (Hz), .06 double amplitude. Shock - 75g, 6 milliseconds (ms).

Class 2 - Altitude - Sea level to 10,000 feet. Vibration - 10-55 Hz, .06 double amplitude. Shock-High impact.

Class 3 - Altitude - Sea level to 70,000 feet. Vibration - 10-500 Hz, 10g. Shock - 75g, 6 ms.

Class 4 - Altitude - Sea level to 70,000 feet. Vibration - 10-2,000 Hz, 20g. Shock - 100g, 6 ms.

Class 5 - Altitude - Sea level to 100,000 feet. Vibration - 10-3,000 Hz, 50g. Shock - 500g, 1 ms.

Class 6 - Altitude - Sea level to 100,000 feet. Vibration - 10-2,000 Hz, 30g. Shock - 100g, 6 ms.

intended Use:

Switches covered by this specification are intended for use in low power dc applications. Also, these switches are intended for use on printed circuit boards, and leads may be soldered or inserted... View More
