Single-pole double-throw temperature controller

Abstract

The invention relates to a single-pole double-throw temperature controller, which comprises a main body, a metal sealing cover and a rear cover, wherein a first disc generates a kick action under the action of temperature and pushes a first insulating push rod to move downwards, so that the first insulating push rod pushes a second movable contact piece to deform downwards, so that a second movable contact of the second movable contact piece is separated from a second fixed contact, a third movable contact of the second movable contact piece is in contact with an auxiliary fixed contact of an auxiliary piece, a second terminal is connected with an auxiliary terminal, a first terminal is disconnected with the second terminal, when the first disc rebounds due to temperature, the second movable contact piece restores upwards, the second movable contact of the second movable contact piece is in contact with the second fixed contact again, and the third movable contact of the second movable contact piece is separated from the auxiliary fixed contact of the auxiliary piece again. Therefore, a single-pole double-throw function of the temperature controller is achieved, two sets of equipment can be controlled at the same time through using the single temperature controller, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of temperature controllers, in particular to a single-pole double-throw temperature controller. Background technique [0002] Thermostat refers to a series of automatic control elements that cause the internal disc of the thermostat to rise or fall in the ambient temperature according to the temperature change of the working environment, and the disc produces a sudden jump action, which produces a conduction or disconnection action, also called Kick-off temperature control switch, temperature protector, temperature controller, referred to as thermostat. The current thermostat products, especially those used in water heaters and oven pipeline heating systems, are mostly single-pole single-throw type. Generally, two independent single-pole single-throw type thermostats are used to control the two devices respectively. This increases the cost of the entire device, so it can be seen that how to provide a single...
