Technical field
The present invention relates to a kind of mechanical switch, be specifically related to a kind of passive and wireless micro-machinery switch.
Background technology
Need the place that the break-make of signal is controlled will use switch. The switch predominantly organic tool formula switch used in electronic circuit and the big class of semiconductor switch two; The advantage of mechanical switch is that its OFF state signals leakiness is very little, and shortcoming is that general volume is relatively big, and switch time delay is longer, has life-span number of times; The advantage of semiconductor switch is that volume is little, switching voltage and switch time delay little, its shortcoming is that standoff voltage leakage is bigger.
Passive and wireless switch refers to and switches on-off by passive and wirelessly realize. Wireless refer to that control part and switch sections do not have a wired connection, passive refer to that switch sections does not have power supply or battery. And existing wireless switching, being generally adopted radio-frequency receiving-transmitting mode is controlled switch, needs battery and power to transmission circuit in switch element. Because containing battery, therefore the service life of this wireless switching is limited.
Micro-machinery switch is the one of mechanical switch, and it adopts micro Process mode to make. Therefore, it remains the feature that the OFF state signals leakiness of mechanical switch is very little, has again the advantage that volume is little, can be used for the break-make of direct current, low frequency or radiofrequency signal and controls. Owing to the execution voltage of micro-machinery switch is higher, being generally higher than 30V, therefore the break-make mode of existing control micro-machinery switch is all wired.
