Description
Technical field
The utility model relates to a kind of switch, in particular to a kind of touching type induction switch.
Background technique
Chinese utility model patent ZL201621035293.8, disclose one kind from lock strap lamp metal button swtich, still,
The button switch of this structure uses mechanical transmission to realize the on-off of circuit, and structure is complicated, and component is various, assembly trouble,
It is at high cost；And existing touching type induction switch, the Current Voltage of input terminal is small, can not be used to switch on or off high current
And voltage, the electric current within 200mA can only be cut off.
Summary of the invention
The purpose of this utility model: in order to overcome the drawbacks of the prior art, the utility model provides a kind of touch sense
Inductive switch, by touch manner realize circuit on-off, moreover, by relay can switch on or off higher electric current and
Voltage.
The technical solution of the utility model includes: a kind of touching type induction switch, includes shell, shell is equipped with capacitive touch
Key, input pin, output pin are touched, relay unit, circuit board control unit, driving unit and electricity are additionally provided in shell
Source control unit；
Wherein, signal is passed to drive for incuding whether hand touches capacitance type touch key by circuit board control unit
Moving cell；
Driving unit, the signal driving relay work for being issued according to circuit board control unit；
Relay unit, for being switched on or switched off input pin and output pin after the signal for receiving driving unit；
Power control unit, for powering to relay unit, circuit board control unit, driving unit.
By adopting the above technical scheme, relay is normally open, when needing to connect input pin with output pin, is used
Hand is touched in capacitance type touch key, and circuit board control unit detects the touch signal of capacitance type touch key, control driving
Relay is closed the connection for realizing input pin and output pin by circuit；Therefore, the touching type induction switch of this structure,
The on-off of circuit is realized by touch manner, moreover, higher electric current and voltage can be switched on or off by relay.
The further setting of the utility model: luminescence unit, luminescence unit and circuit board control are additionally provided in the shell
Unit connection processed, capacitance type touch key are equipped with transparent area.
Using above-mentioned further setting, the luminescence unit of setting, light can be projected by transparent area, can both may be used in this way
It is more beautiful to play certain illuminating effect；Switch can also be understood in real time convenient for user in closure or disconnects shape
State.
The further setting of the utility model: the capacitance type touch key and the circuit board of circuit board control unit it
Between connected through spring.
Using above-mentioned further setting, the signal of capacitance type touch key is passed to by circuit board control list by spring
Member, stability is good, and induction of signal is strong.

Specific embodiment
As shown in figures 1-8, a kind of touching type induction switch, includes shell 1, and shell 1 is equipped with capacitance type touch key
2, input pin 3, output pin 4, be additionally provided in shell 1 relay unit, circuit board control unit, driving unit, shine it is single
Member and power control unit, the input terminal of relay unit and the output end of driving unit connect, power control unit, driving
Unit and luminescence unit are connect with circuit board control unit, and capacitance type touch key 2 is equipped with transparent area 21；Wherein, electric
Whether road plate control unit, induction hand touch capacitance type touch key, signal are passed to driving unit；Driving unit is used
In the signal driving relay work issued according to circuit board control unit；Relay unit, for receiving driving unit
Signal after be switched on or switched off input pin and output pin；Power control unit, for being controlled to relay unit, circuit board
Unit, driving unit, luminescence unit power supply, between the capacitance type touch key 2 and the circuit board 6 of circuit board control unit
It is connected through spring 5.
Wherein, relay is normally open, when needing to connect input pin with output pin, is touched with hand in capacitor
On formula touch key-press, circuit board control unit detects the touch signal of capacitance type touch key, controls driving circuit for relay
Device closure realizes the connection of input pin and output pin；When needing to disconnect input pin and output pin, it can touch again
Twice, circuit board control unit is disconnected through the i.e. controllable relay of driving unit for capacitance type touch key or continuous touch.
Therefore, the touching type induction switch of this structure, the on-off of circuit is realized by touch manner, moreover, can by relay
To switch on or off higher electric current and voltage.
