Working principle and installation precautions of jump type temperature control switch

Jump type temperature control switch is based on the temperature of the object to be controlled to determine the switch on and off; According to its action principle is divided into: bimetallic, pressure and thermal ferrite type. Bimetallic jump type temperature switch: all kinds of metals have thermal expansion and contraction characteristics, and different metal with the temperature change of the expansion coefficient is not the same, bimetallic jump type temperature switch is based on this principle to work, bimetallic sheet by the upper "high manganese alloy § and the lower" steel § composition. The former expansion coefficient is dozens of times the latter, respectively known as the "active layer § and" passive layer §, at normal temperature copper and spring plate contact A and B contact is connected to the contact, the whole circuit in the state of connected. When the temperature rises, the active layer expands more than the passive layer, and the bimetallic sheet bends downward. When the temperature rises to a certain degree, the circuit is disconnected. Cooling to a certain degree of bimetallic sheet recovery, circuit connected.

Precautions for installation of jump type temperature control switch:

1. During installation and use, do not touch the shrapnel and temperature sensing part, otherwise it will lead to the temperature misalignment of the protector, poor contact and abnormal action.

2. During installation, the contact surface should be facing the lee side, so as not to affect the function of the shrapnel and the accumulation of dust attached to the surface of contact A and B, resulting in poor conduction.
