Table 3.

Advantages and disadvantages of electrical connections.

	Advantages	Disadvantages
Pin	Prevent lateral movement	Easily breakable if thin
	Large electrical connection surface	Affected adversely by particles
	Latching after connection	Needs precise guiding
	Transfer of energy and signals	Sizes dependent on power loads
Tab	Large angular/displacement	No latching after connection
	tolerance	Sizes dependent on environment
	Power available before latch fully closed
	Tolerance against particles
	Transfer of energy and signals
Slip rings	Applicable for high power	Wear of sliding contact
	Transfer of energy and signals	High assembly space
	High torque at start	Unsuitable for short term
	Low starting current	operation
	High over loading capacity	Long initial phase
	Rotating connection
Wireless	Non-contact transmitter receiver	Large surface for energy
	Resistant against affecting by	absorption
	particles	Weight penalty
	Insensitive to interference	Loss of energy
	Good stability
