Description

Switch with two-way signal

This creation is a kind of switcher, especially the switcher with two-way signal used in motor vehicles.

Existing switches currently installed on motor vehicles provide a one-way signal, that is, the switch can be switched to the first state or the second state. If the switch is normally in the first state, it can transmit a signal through electrical conduction. When the switch is switched to the second state, the electrical conduction in the first state is released and no signal can be sent out.

Existing switches only show electrical conduction in the first state to transmit signals, and in the second state there is no electrical conduction and cannot transmit signals. Therefore, the signals generated in the first state can only be used as an indication of other states and pass the motor vehicle. However, the existing switch does not generate a signal in the second state and cannot provide subsequent applications, so further improvement is needed.

The main purpose of this creation is to provide a switcher with a two-way signal, so as to improve the problem of poor applicability of the existing switcher that only provides a one-way signal.

In order to achieve the purpose of the foregoing disclosure, the switcher with two-way signals of the present creation includes: a housing in which an assembly space is formed, and a hydraulic input space and an output space communicating with the assembly space are formed on the housing. The assembly The space is located between the hydraulic input space and the output space; A pin assembly, which is disposed on the housing and located in the assembly space, the pin assembly includes a first pin unit and a second pin unit that are spaced apart, and two opposite ends of the first pin unit A first input terminal and a first output terminal are formed respectively. The two opposite ends of the second pin unit respectively form a second input terminal and a second output terminal. A switching gap is formed between the first output end and the second output end extending into the output space; and a switching assembly, which is movably disposed on the housing and extends into the switching gap, and passes through the hydraulic pressure The hydraulic pressure of the input space moves, and the first input terminal or the second input terminal is selectively electrically connected.

In the above, the switch can be arranged on the motor vehicle and connected to a hydraulic structure through the housing. The hydraulic pressure applied to the hydraulic input space of the housing through the hydraulic structure drives the switch assembly to switch and electrically connect to the first The input terminal or the second input terminal can emit a first signal in the first state electrically connected to the first input terminal, and can emit a second signal in the second state electrically connected to the second input terminal, so the switch Switching to different states can correspondingly send out different signals, and provide different signals as the basis for subsequent applications.
