Mechanical Decade Counters - Small Size - Pack of 5

Click, click, click! I just can't stop having fun with these mechanical decade counters. Each order includes five individual counters that snap together, allowing you to connect as many or as few as you like. Each counter has two buttons: an up - counter and a down - counter. When the count reaches 9, it resets to zero. The back of each counter features a PCB with 11 contacts: one common contact and 10 that are shorted to the common one as the counter progresses through the numbers. These counters make for an interesting and useful interface. They are the smaller size, with a bezel size of 1.85' x 0.94' for the set of 5 counters with 2 end caps.

Using these mechanical decade counters is a breeze. First, snap the counters together according to your needs. You can connect as many or as few as you like. To count up, press the up - counter button. To count down, use the down - counter button. Once the number reaches 9, it will automatically circle back to zero. When handling the counters, be gentle as they are mechanical devices. Avoid dropping or applying excessive force. For maintenance, keep them in a dry and clean environment. If you notice any dust on the PCB at the back, you can use a soft, dry cloth to gently wipe it. That's all there is to it, and you'll enjoy using these fun and useful counters for a long time.
