Description

Technical Field

[0001] The utility model relates to a multifunctional key button switch. Background Art

[0002] A key button switch is a switch that can control electrical appliances or equipment by rotating or pressing a key button, which brings preventive effects to various special industries (elevators, security, electromechanical equipment, medical equipment). The structure of a key button switch generally includes: a base, a lock core, a sheath, a threaded sleeve, and a knob core. When the existing key button switch is rotated after the key is inserted, the key's removable operation and non-removable operation are fixed and cannot be changed. If the rotation position of the key's removable operation and non-removable operation is to be changed, a different sheath needs to be replaced. This makes it very inflexible and inconvenient for users to use it in different usage scenarios, and the adaptability is poor. On the other hand, the connection structure of the sheath still needs to be strengthened to make the connection between it and the components more compact and the action more reliable. Therefore, it is necessary to improve and optimize the sheath of the key button switch. Utility Model Content
