1、 Overview

F13 series auxiliary switch is suitable for closing opening control of high-voltage switch spring mechanism indication of interlocking signal. It can also be used as conversion combination switch. It is the preferred component of operating mechanism.

2、 Conditions of use

1. Ambient air temperature: - 40 ℃ ~ + 40 ℃;

2. The altitude of the installation site shall exceed 2000m;

3. The conditions are as follows: the average value of relative humidity measured within 24 hours shall exceed 95%; the average value of water vapor pressure measured within 24 hours shall exceed 2.2kpa; the average value of monthly relative humidity shall exceed 90%; the average value of monthly steam pressure shall exceed 1.8kpa, the condensation on product surface due to temperature change shall be considered;

4. The acceleration should be greater than 15m / S;

5. The air is obviously polluted by dust, smoke, corrosive combustible gases, steam salt spray.

5、 Structural features

1. There are DC contacts specially used to control DC 220 V 110 V closing coil opening coil, the breaking current can reach DC 220 V, 3 a;

2. The contact is silver alloy bridge type double break point structure. Compared with the existing auxiliary switch, it has the advantages of reliable connection, anti-oxidation corrosion resistance of contacts;

3. It can be made into various delay contacts, users need to provide clear technical requirements;

4. This series of auxiliary switch has the advantages of simple structure, easy to use long service life. It is an ideal replacement product for mechanism miniaturization.
