Micro Switch has lots of types, what we have are KW3 series, KW12 series, KW10 series, KW1 series, KW2 Series and Z Series. Also, some people think that the detector switch and tact switch belong to microswitch. The cost of a micro switch is pretty different according to its material and function. There are some micro switch cost types below for your reference.
Micro Switch KW3
The basic material of KW3 has PPT, Brass, Ag, Aluminum, Stainless Steel, Beryllium Bronze, Phosphor Cooper. The current of KW3 series is from 0.1-25A 125/250VAC. Its mechanical life is over 1000000 times, and electrical life is over 10000 times or 50000 times. The cost of KW3 is pretty different, from USD 0.1-0.3, depending on the actual current. We need to thicken the silver of contact to improve the microswitch life.
Micro Switch KW12
Our KW12 micro switch is made of PPT, Brass, Ag, Aluminum, Stainless Steel, Beryllium Bronze, Phosphor Cooper. The current of KW12 series is from 0.1-10A 125/250VAC. And, the mechanical life is over 1000000 cycles, and electrical life is over 10000 cycles. The price of KW12 micro switch is from USD 0.1 to 0.2, up to the actual current and requested electrical life.
Micro Switch KW10
Chinakel KW10 micro switch is made of Brass, PA66, POM, Copper, and Phosphor Copper. 0.1-3A is KW10 current range. Regularly, micro switch KW10 is used for mouse switch, its life can be over 3000000 times or 10000000 times. And the cost is from USD 0.06 to 0.16 for mass production.
Micro Switch Z
Chinakel Z Micro Switch can hold 5A 250VAC. The cost is from USD 0.6 to 1.
IP67 Micro Switch KW1
Chinakel KW1 Micro Switch can reach IP67 protection level. It’s made of PPA, Silicone, stainless steel wire, copper. Most of KW1 is used in the car parts. It’s current is 0.1A 125/250VAC or 3A 12VDC. KW1 life can more than 300000 cycles.The cost is from USD 0.25 to 0.4.
IP67 Micro Switch KW2
KW2 Micro Switch is also a waterproof microswitch. KW2 life can over 500000 cycles. The cost is from USD 0.32 to 0.5.
Detector switch is the part of the microswitch, its current is 100mA 30VDC. The life of detector switch can more than 50000 times, some of this can over 200000 times. The cost is from USD 0.05 to 0.2
The tact switch is also a mini microswitch. The cost is from USD 0.03 to 0.1
