Contribution margin is a measure of operating leverage: the higher the contribution margin is (the lower variable costs are as a percentage of total costs), the faster the profits increase with sales.
What is a snap switch also known as Snap Disc or snap action thermostat? Snap Disc, or snap switch thermostats are bimetal mechanical thermostats that function via the thermal expansion and contraction of a bimetal disc that âsnapsâ from a convex to a concave shape at a set temperature. When the disc âsnapsâ, it either completes or interrupts a circuit.
SnapStats (0Â°F â 300Â°F): Contact movement in the temp switch is achieved using a bimetallic snap disc. Snap action provides shock and vibration immunity and a broader differential. Set point range: 0Â°F-300Â°F (-17.8Â°C-148Â°C)View options by configuration: Surface Mount.
