Double-speed button switch: The same button can be pressed twice, at a speed of 50%, and then at a speed of 50%. This means that the same button can be double-tapped, with two gears, used on a two-speed motor.
Double-speed button: The double-speed button is made according to the customer's electric
hoist's requirement. Before ordering the double-speed button, make sure that several groups of buttons are double-speed.

I. Scope of application
It is suitable for the circuit control system with AC 50Hz or 60Hz, voltage to 380V and DC working voltage to 220V. Applicable to open air, rain and snow, dust damage to the environment, such as cranes, electric
hoists and other equipment for remote control purposes. The product meets GB 14048.5 standard.
Type and Meaning
& ldquo; A” denotes with the main power switch, & ldquo; no letter & rdquo; denotes without the main power switch < br />.
& ldquo; B” means to bring up and stop the switch. & ldquo; K” means with start and stop switch < br />.
3. Normal working conditions and installation conditions
1. The ambient air temperature ranges from - 5 degrees to + 40 degrees, with an average of no more than + 35 degrees within 24 hours < br />.

1. Structure and properties
COB series buttons adopt full plastic shell with beautiful appearance and reasonable structure. The product is equipped with rubber cable sheath and waterproof strip, which has good dust and rain proof performance < br />.
In addition to & ldquo; start & rdquo; & ldquo; stop & rdquo; button and circuit switch & ldquo; on & rdquo; & ldquo; self-locking button & rdquo; button, its button has automatic reset performance, and has positive and negative control mechanical interlocking mechanism, which not only simplifies the circuit, but also effectively protects the operation of circuit and equipment, in order to prevent circuit failure more reliably, button & ldquo; and & ldquo; Self-locking button & rdquo; button, can cut off the total power supply < br />.
Instructions for Use < br />
Remove the end cap, put in the sealing sheath, and fasten them to the end face of the button by screw < br />.
After removing the bottom cover and inserting all control wires into the sealing sheath, the buttons are tightened one by one on the terminals of the buttons according to the electrical schematic diagram < br />.
Check or test whether the wiring is correct. If everything is normal, tie the lead and fix it. Finally, reinstall the bottom cover.
