KSD301系列突跳式溫控器是小型雙金屬片溫控器，屬溫度繼電器類器件。利用碟型雙金屬

片在溫度作用下產(chǎn)生瞬間跳動(dòng)的原理，通過機(jī)構(gòu)的作用，使觸點(diǎn)迅速動(dòng)作，達(dá)到斷開或接通電

路的目的。其工作溫度固定，無(wú)須調(diào)整；動(dòng)作可靠干脆，電弧小；使用壽命長(zhǎng)；無(wú)線電干擾小

。

KSD301 snap action thermostat is small-size bimetal thermostat series with a

metal cap, which belongs to thermal relays’ family. The main principle is that

one function of bimetal discs snap action under the change of sensing temperature.

The snap action of disc can push the action of the contacts through the inside

structure, and then caused on of off of the circuit finally. The main

characteristics are the fixation of working temperature, the reliable snap action,
