Versatile Usage of Mechanical Timers
Mechanical timers, readily available in home improvement centers for a nominal price, are ideal for cyclically switching devices on and off throughout the day. Their applications extend across a wide array of devices, including indoor and outdoor lamps, lighting for bird cages and aquariums, sump pumps, battery chargers, and more. These timers offer simplicity and effectiveness for various household needs.
Extended Control with Multiple Timers
If you require control over a period longer than the standard 24 hours, a practical solution involves utilizing two timers, with the second one plugged into the first (refer to the photos for visual guidance). To determine the capabilities of this setup, it’s crucial to assess how frequently the load needs switching. For instance, if the first timer features 48 tabs, the shortest ‘on’ time possible is 30 minutes within 24 hours. Consequently, the second timer will operate for 30 minutes every day, allowing for a complete cycle duration of up to 48 days. Devices like diving torch chargers can be linked to this second timer.
To ensure the ‘on’ time of the second timer doesn’t exceed 24 hours, it’s imperative to keep its duration shorter than that of the first timer. If a 48-day cycle isn’t sufficient, incorporating a third timer is an option. With three timers in place, the maximum cycle time extends to 2304 days, roughly 6.5 years for a single ‘on’ time.
As depicted in the photos, the second timer might clash with the tabs of the first timer when stacked vertically. This issue can be circumvented by rotating the second timer 180 degrees relative to the first one.
Mechanical Timers: Efficient and Long-lasting
Mechanical timers serve the purpose of activating devices after a specific time interval. They operate without requiring electrical power and boast the advantage of being storable for extended periods.
- automatic milling machines
- periodic lubrication
- animated shop-window displays
- staged start-up of pumps
- automatic presses
- industrial washing machines
Mechanical timers are also used in motors, blowers, lighting, and control valves as well as in banking, retail, irrigation, and general industrial applications.
