High-temperature Basic Switch
TZ
Stable Operation at an Ambient
Temperature of 400
°C
Incorporates a ceramic insulator, cobalt-alloy spring, and special-
alloy contact, thus ensuring high contact reliability at high
ambient temperature.
Smoothly operates at an ambient temperature of 400
°C.
Be sure to read Safety Precautions on page
3 and Safety Precautions for
All Basic Switches.
Ordering Information
Note: The levers and rollers are made of stainless steel.

Ratings
Note: 1. The above current ratings are the values of the steady-state current.
2. Inductive load has a power factor of 0.4 min. (AC) and a time constant
of 7 ms max. (DC).
3. Lamp load has an inrush current of 10 times the steady-state current.
4. Motor load has an inrush current of 6 times the steady-state current.
5. The above ratings are tested under the following conditions.
Ambient temperature: 20
±2°C
Ambient humidity: 65
±5%RH
Switching frequency: 20 times/min
Characteristics
*1. This operating speed applies to switches with pin-type pushbuttons.
*2. This refers to a malfunction period of 1 ms max.
