Do you have the same type of handbrake as L01 handbrake?

A customer inquired about the coil of the 200 mA X-ray machine and sent us a picture of the product. I saw the exposure x ray hand switch in his picture, which is similar to our L01 handbrake.
Our L01 handbrake is a two-stage handbrake switch. Two similar handbrake switches are L02 and L04 handbrake switches.

The shape of L02 hand brake switch is very similar to L01 handbrake, both of which are streamlined, and L04 hand brake has round edges.
The first gear of the L01 handbrake is the preparatory gear. Only by pressing two gears continuously can the exposure be completed. Preparatory file effectively prevents operator’s mis-triggering behavior.
